bug#41668: Failing test: gui-installed-desktop-os-encrypted

Hey Ludo,

I used a custom re-implementation of "invoke/quiet" printing every line
on the syslog port. Maybe, we could enable such a mechanism only during
the tests.

Yes, that's for sure making the debug more comfortable!

Totally agree. When submitting patches to Linux for instance, the CI is
able to reply to the patch mail, and warn about any failures. An other
difference is that patches are often kept in the maintainer 'staging'
branches until the CI is over.

I don't know if Guix is a big enough project to appoint some maintainers
that would periodically merge their branches to 'master' or if it would
just be a huge burden. Something we need to discuss in the future maybe.

Anyway, thanks for your fast review :)
